Interpretive Summary: Vegetable amaranth is a warm-season green that is grown for local markets and also imported into the United States. The production potential for vegetable amaranth has not been documented in high EC (saline) soils common in the Southwestern U.S. This study demonstrated that vegetable amaranth was moderately tolerant when grown in high salt amended soil. Increasing levels of supplemental nitrogen fertilizer improved yield and leaf color.
